Using EOS-Dedicated, External Speedlites
108
Before attaching an external Speedlite, retract the built-in flash if it is
popped up.
If the EX-series Speedlite’s firing mode is set to TTL autoflash with the
Custom Function, the Speedlite will not fire.
If autofocus cannot be achieved, the external, EOS-dedicated
Speedlite’s AF-assist beam (if the Speedlite has an AF-assist beam) will
be emitted automatically (except in the <5> <7> modes).
The camera is a Type-A camera that can use all the features of EX-
series Speedlites.
Using Non-Canon Flash Units
The camera can synchronize with compact, non-Canon flash units at 1/
250 sec. or slower shutter speeds. With large studio flash, the sync
speed is 1/125 sec. or slower. Be sure to test the flash unit beforehand
to make sure it synchronizes properly with the camera.
The camera’s PC terminal is provided for flash units having a sync
cord. The PC terminal is threaded to prevent inadvertent disconnection.
The camera’s PC terminal has no polarity so you can connect any
sync cord regardless of its polarity.
Sync Speed
PC Terminal
If the camera is used with a flash unit or flash accessory dedicated to
another camera brand, the camera may not operate properly and
malfunction may result.
Also, do not connect to the camera’s PC terminal any flash unit requiring
250 V or more.
Do not attach a high-voltage flash unit on the camera’s hot shoe. It might
not work.
A flash attached to the camera’s hot shoe and a flash unit connected to the
PC terminal can be used at the same time.
